If my memory serves me correctly, a NAT allows one IP address to represent an entire group of computers.
Nodes that accesses an ISP have a unique MAC address within their network adapter(s). This allows the ISP to distinguish how many computers are acessing the internet , and also allow them to discontinue service to certain computes by blocking service to specific MAC addresses on the one IP address.
The only way (that i know of anyways) to stop this is by using a MAC clone, which masks every computer accessing an outside network with the exact same MAC address, thus hiding the individual computers using the network.
